Call the original chrome javascript API and return a Promise.

If you build your project with webpack, then you can install chrome-call from npm:

npm install chrome-call 

then you can import it in your project:

// es6 import chromeCall from 'chrome-call' // commonjs const chromeCall = require('chrome-call')

Download chrome-call.js from unpkg(min version), then reference it in your html:

<script src="path/to/chrome-call.js"></script> <!-- now you will get a global variable named chromeCall --> <sciprt> typeof chromeCall // function </sciprt>

When you do:

const promise = new Promise((resolve, reject) => { chrome.storage.local.get('key', items => { if(chrome.runtime.lastError){ reject(chrome.runtime.lastError) } else { resolve(items) } }) })

It's equal to:

const promise = chromeCall(chrome.storage.local, 'get', 'key')

That's really simple, right?

Some Chrome API methods has more than one arguments, then pass an array of params for the third argument:

chromeCall(chrome.tabs, 'sendMessage', [tabId, message, options])

Most of chrome API only has zero or one argument in callback, but someone not, such as chrome.hid.receive.

In this situation, pass true as the fourth argument, then the value of promise will be an real Array:

import chromeCall from 'chrome-call' chromeCall(chrome.hid, 'receive', connectionId, true) .then(args => { Array.isArray(args) // true const reportId = args[0] const data = args[1] })
